As a result, the library on the DVD-RAM can be restored on the HDD, so that the library information can be restored even when the HDD fails.
[0110]
(8) Automatic registration in the library
Next, a case where library information according to the present invention is automatically registered will be described. FIG. 15 is a flowchart for explaining the operation in the case of performing automatic registration in the library of the library function according to the present invention.
[0111]
The library information according to the present invention has been described earlier as including information registered manually in (4). However, the basic library information is automatically created after the recording process is completed, and is registered / registered. It will be preserved.
[0112]
As shown in the flowchart of FIG. 15, when the recording process is completed for a predetermined optical disk (S101), the library information is stored in the library information management unit 16- of the microcomputer block 16 after the recording end process (S102). Under the control of 1, after confirming whether the number of library information is the upper limit (S103), if the upper limit of the number of library information is reached, a message that the library is full is displayed (S105). If the upper limit is not reached, for example, as shown in (a) of FIG. 2, input from the user such as a disc number, recorded date, day of the week, hour, minute, and channel number is required. Information that is not to be registered is automatically registered (S104). Here, it is also preferable to extract some information from the thumbnail information and register it as library information.
[0113]
As a result, library information is automatically generated and added to the library when an object is generated upon completion of recording or the like, so that the user does not need to register each time.
[0114]
(9) Automatic deletion from the library
Next, a case where library information according to the present invention is automatically deleted will be described. FIG. 16 is a flowchart for explaining the operation when automatic deletion is performed from the library of the library function according to the present invention.
[0115]
In the library information, if the title is deleted from the disc, it is preferable that the corresponding title is deleted from the library in accordance with this and the library is updated in accordance with the current state.
[0116]
Therefore, in the flowchart shown in FIG. 16, the library title deletion process (S111) is performed. When the title deletion process in the optical disk is first performed (S112), the library information management unit 16 of the microcomputer block 16 is responded accordingly. Under the control of -1, it is confirmed whether or not the deleted title exists in the library in the hard disk (S113). If it does not exist, the deletion process is not performed, but if it exists, it is automatically deleted from the library (S114).
[0117]
As a result, when an object on the optical disk is deleted, the library information is automatically deleted from the library information, so that the user does not have to delete each object and the library is automatically updated according to the current image. .
[0118]
(10) Automatic library correction
Next, the case where the library information according to the present invention is automatically corrected will be described. FIG. 17 is a flowchart for explaining the operation when the library of the library function according to the present invention is automatically corrected.
[0119]
In the library information, if the title name in the disc is corrected, the corresponding title in the library is corrected accordingly, and the library is preferably updated according to the current situation.
[0120]
Accordingly, in the flowchart shown in FIG. 17, this library title correction processing (S121) is performed first when the title in the optical disk is corrected (S122), and accordingly, the library information management unit 16 of the microcomputer block 16 corresponds to this. Under the control of -1, it is confirmed whether the corrected title exists in the library in the hard disk (S123). If it does not exist, the correction process is not performed, but if it exists, the title information in the corresponding library is automatically corrected (S124).
[0121]
Thus, since the library information is automatically changed when the object on the optical disk is changed, the user does not need to make corrections one by one, and the library is automatically updated according to the current image.
[0122]
(11) Password function
Finally, a case where a password is set in the library information according to the present invention will be described. In the library information as described above, a password can be set for the whole or a part of the library information. For example, this process is performed under the control of the library information management unit 16-1 of the microcomputer block 16, and one password is set for the entire library information. Alternatively, one password is set for a specific library among a plurality of library information.
[0123]
Thereby, a specific person in the family can construct library information that can be browsed only by the other family in secret.
[0124]
【The invention's effect】
As described above in detail, according to the present invention, a library that collects library information related to image information of a plurality of optical discs is provided in the hard disk, so that image information that has conventionally relied on user's memory can be identified and managed. It is an object of the present invention to provide an image recording / reproducing apparatus having a library function that can be easily performed.
[0125]
Also, by storing the title information of the DVD-RAM and HDD as a library in the main body, it is possible to perform a unified management that can search for the titles of a plurality of DVD-RAM and HDD images collectively without distinction.
[0126]
In addition, by storing this library information in the HDD, it becomes possible to store a large amount of library information in a form that can be easily retrieved.
[0127]
In addition, by providing information for disc identification in this library information, it is possible to recognize that the correct disc is not inserted during playback, and it is possible to display the disc number to be inserted to the user. become.
[0128]
Further, by providing the library information with title identification information, it is possible to search for coincidence between the library information and the title information on the disc, and to recognize whether or not the corresponding title exists on the disc.
